I'm trying to make a subscription list in a navigation view where when you subscribe to an item the category of that item will show in the navigation view, and when you unsubscribe from every item in a category it should remove that category from the navigation view's menu.
Problem is to remove the category I need to clear the whole list and then add item by item, but the navigation view doesn't hold just the list of subscription: It also allows the user to navigate through different activities. If I use the menu.clear() method the navigation items will be removed as well.
To add them again, I need as parameters the item's ID, the group's ID, the Order int and the title. I know where to get the IDs and titles since they are coded in the XML, but I know not how to find the order in the list, or what that is.
Also if you have an easier or better way to resolve this, please let me know.
I was told the RemoveItem could cause problems, so I tried to avoid that.
What I did was find the item and group ID from the items I didnt want to get removed, clear the list, and then add the items with a made up order (I just made a variable and incremented it for each item I needed), then add the item names I needed for the items without interaction.
